Can I use time-controlled charging together with PV surplus power?
Yes, you can use time-controlled charging together with PV surplus power. But there is no need to configure any settings manually when smart wallboxes, like the go-e Charger, make it happen automatically in ECO mode. The charger will first use your PV surplus and then fall back on grid electricity during your chosen time slots or when the price per kWh drops below your defined limit.
